摘　　要：靖安油田属于典型的低渗透油藏,具有典型的三低特征,油藏进入中含水期,水驱规律、剩余油分布特征较为复杂,调整难度大,因此研究剩余油对低渗透油藏进入中高含水期具有较为重要的意义。本文以靖安油田最具有典型代表的五里湾长6油藏为例,深入研究进入中高含水期剩余油分布特征。五里湾长6油藏已进入中高含水开发阶段,由于不同开发阶段的生产制度、开采速度、注采矛盾、开发特征等原因影响,剩余油分布认识不清,致使剩余储量动用难度增大,严重影响了采收率的提高,本文主要从动态分析法、数值模拟法、沉积相法、动态监测法等国内外成熟的剩余油研究方法有机的结合研究五里湾长6油藏剩余油富集规律,并通过认识的规律指导挖潜剩余油,取得了良好的开发效果,对其它类似油藏的后期开发有较强的指导意义。Wuliwan bay reservoir has entered the development phase in high water cut,due to the different stages of development of production systems,the exploitation of the speed of injection and production of contradictions,and so the reasons for the development of the characteristics of the impact of clear understanding of the distribution of residual oil,with the result that the remaining reserves are difficult to use seriously affected the improvement of oil recovery,so study the distribution of remaining oil enrichment is particularly important.Through a single means of remaining oil distribution,it is difficult to accurately describe the distribution of residual oil,so this article from the dynamic analysis,numerical simulation,sediment-phase method,dynamic monitoring of law at home and abroad,such as the remaining oil in mature organic combination of research methods research Wuliwan Chang 6 enrichment of remaining oil,and through understanding of the law to guide the remaining oil potential,the development of good results,similar to other reservoirs of the late development of a strong guiding significance.
